The upsampling takes place before Dolby TrueHD encoding. The 96k upsampling process applies higher sample rates and increased playback quality through an advanced apodizing filter that masks undesirable digital artifacts in 48k material.Dynamic range control enables reduced peak volume levels without impacting overall sound quality.Since a single Dolby TrueHD stream can contain up to three separate mixes - a 7.1-channel mix, a 5.1-channel mix, and a two-channel stereo mix - you can tailor each one for optimum listening on any playback system.Gives the Blu-ray content creator the ability to include a companion Dolby Digital (640 kbps) 5.1-channel theatrical mix on 7.1-channel Dolby TrueHD titles.Provides superior 7.1 downmix overload detection and protection.Includes dynamic range control, enabling reduced peak volume levels without loss of overall sound quality - ideal for listening without disturbing others.Maintains consistent dialogue levels when changing between Dolby TrueHD and Dolby Digital programming.

Delivers up to 16 channels of pristine audio at studio-master quality.

Transfers data at bit rates of up to 18 Mbps for unmatched sound quality.

Dolby TrueHD lossless audio advanced features The result: you experience entertainment as it was meant to be heard. It also features advanced 96k upsampling to produce the highest-quality Blu-ray audio from material originally recorded at 48k.

On Blu-ray, Dolby TrueHD supports up to eight full-range channels of 96 kHz/24-bit audio and six full-range channels of 192 kHz/24-bit audio. Dolby TrueHD corrects this problem by applying higher sample rates and increased playback quality through an advanced apodizing filter. Unfortunately, the 48k recording process can introduce an unnatural harshness or edginess to the sound during the conversion from analog to digital.

Most movie and TV soundtracks are recorded at 48k. What this means for you is the best possible sound from Blu-ray Discs™ and streamed or downloaded sources. These enable 100 percent lossless audio in files half the size of uncompressed pulse-code modulation (PCM). Every detail of the original recording is preserved because Dolby TrueHD reproduces audio bit-for-bit identical to the studio master.ĭolby TrueHD accomplishes this using a suite of highly sophisticated compression technologies. Dolby TrueHD ensures that what you hear at home is completely accurate to the artist's vision - not an approximation or a recreation, but the full audio experience. A filmmaker can spend years working to make every detail of a movie perfect, and this includes the audio.
